A simple, fast HS256 JWT(JSON Web Token) implementation in PHP. Since the rfc7519 only requires to implement "HS256" and "none" and "none" is not a secure token, HS256 should cover most of the use cases. If you just want to encode/decode a spec compliant JWT, this project is definitely what you want.
Since it does not available as a composer/pecl package. You can just copy jwt.php to your project's library directory
and import it using require_once.
<?php
require_once 'jwt.php';
$key = 'I love PHP!';
/* Encode using array */
$jwt = jwt_encode(['foo' => 'bar', 'bar' => 1234567890], $key);
echo $jwt . PHP_EOL;
/* Encode using JSON string */
$jwt = jwt_encode('{"foo":"bar","bar":1234567890}', $key);
/* Decode */
$json_object = jwt_decode('eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJmb28iOiJiYXIiLCJiYXIiOjEyMzQ1Njc4OTB9.yxaKARhiuhCElP3cnj3KFtgQamqZcBktBGjcXIxspC8', $key);According to the benchmark script, the implementation is about 50% faster than firebase's when benchmarking on MacBook Pro 13 2020.

It takes a lot of time to create and maintain a project. If you think it helped you, could you buy me a cup of coffee? 😉
